PULP IBEATER.

Application filed. February This invention relates to pulpbeating en a gines and has for its object to provide an improved construction, combination and arrangement of parts whereby an engine of this character may be more economically operated and rendered more effective in its action. I a

7 One of the obj ects of the present invention is to provide an improved mount for the 19 pulp-beating roll which operates in a suitable raceway "for breaking up and finely comminuting the material from which the pulp is to be formed.

, Another object of invention is to provide means of improved construction whereby the material which usually, tends to collect and become wadded in between the ends of the pulp-beating roll and the adjacent side walls between which said roll revolves, may be 29 broken and cut up into small parts which are thus made ready to be included in the I pulp-forming operation.

Other and further objects of invention will appear in the specification and be pointed out in the appended claims, referones being had'to the accompanying drawings which illustrate a preferred embodiment of our invention and in, which Figure 1 is a top plan view of the pulpbeating engine with its top plate or cover shown in section; t

Figure 2 is a transversesection of the same with parts shown in elevation;

Figure 3 is an enlarged vertical section on the line 3-3, of Figure 2; p

Figure 4 is an enlarged vertical section on the line 1-4, of Figure 2 Figure 5 is a perspective view of the cutters and their mounts removed;

Figure 6 is an enlarged detail section on the line 6-6, of Figure 2.

According to the embodiment of our invention shown on the drawings, the tank comprises a bottom wall 1 with flat side walls 2, 3 and half-circular end walls 4. A

central pier 5 of elongated cross-section and rounded at opposite ends forms an endless raceway 6. Said pier 5 is provided with a central well or depression 7 within which is mounted a bearing 8 for one end of a pulpbeating roll shaft 9, the other end of said shaft being journalled in a bearing 10 which surmounts a pillar 11. Keyed to the shaft 9 is a pulley 12 over which passes a belt 55, 13 for driving the pulp beating r, 1927. Serial No. 166,337.

Mounted upon the shaft 9 between the laterally-spaced side walls 2 and 14, the latter being in the present embodiment of my invcntion, a constituent portion of the central pier 5, is a pulp-beating roll or drum 15 provided with radial blades 16. It will be seen by an inspection of Figure 2 that the laterally-spaced side walls 2 and 14 are provided with suitable extensions 2 and 14 upon the upper edges ot which may be seated a top plate or cover 17. As shown in Figures 1 and 2, the opposite ends of the roll or drum 15 are spaced from the laterally-spaced side walls 2 and 14: to aiford freedom of movement to the rotating drum. These spaces, however have been the source of much trouble due to the accumulation of material around the shaft 9 and between the drum 15 and side walls 2 and 14;. i To overcome these drawbacks several devices have been employed. According to the present invention, this trouble is overcome by means of cutters of-improved construction which are now to be described.

As shown best in Figure 4E, the'laterallyspaced side walls 2 and 14 with their extensions 2 and 14 are provided with upwardly opening vertical slots 18, said slots being provided at the bottom with half-round cavities 19 for the accommodation of the shaft 9 which extends thru the lower ends of said slots. According to the present embodiment of my invention. the walls of slots 18 are preferably formed by cast iron plates 20 which are arranged in suitable rectangular recesses extending from the horizontal plane thru the axis of shatt 9 to the upper edges of side walls 2' and 14'. The tank including pier 5 and side walls 2 and 14. may be advantageously constructed of cement. Arranged in each of the slots 18 is a box -like frame 21 of channeled cross-section as may be seen from an inspection of Figures 5 and 6. Said frames 21 are thus provided with lateral flanges 21 which are secured to the oppositely-disposed cast-iron plates 20 by means of bolts 22 which extend thru said flanges and plates and into the cement behind said plates. Presented ,inwardly from each of the frames 21 are a plurality of radially-spaced blades or cutters 23 preferably of rectangular crosssection as shown. The bottom ed e 0t the flat plate of frame 21 and that of tnelowermost blade or cutter 23, are provielsdwith arcane recesses 24 so that these parts may be brought into close juxtaposition to shaft 9. Secured to the outer face of each end of the pulp-beating roll or drum 15 by means of bolts 25, is a radial cutter plate 26 which as shown in Figures 3 and 5 is provided with outwardly-presented blades or. cutters 27, said cutter plate being so positioned on the end wall of the roll or drum and said blades or cutters being radially-spaced in such away that as they revolve about the axis ofv shaft 9,. they overlap and pass between the fixed blades or cutters 23' carried by cutter frames 21.
